Vtec problems
Ok so ill just get to it vtec doesn't work, I bought this car with an ls/vtec swap already in there and I'm guessing vtec was all in my head the whole time I was driving the car don't laugh at me for that but I saw that a connector was missing for the vtec pressure switch so I went and got a connector for it and wired it up, the black im guessing is ground so I unscrewed a bolt on the body and the other colored wire goes to the ecu and that went to d6 right on the jumper harness. Its a 99 integra obd2 on hondata p28 for whoever doesn't know but its hooked directly into the harness.
Now to the solenoid I heard you can check to see if u have a bad solenoid or not by seeing if it clicks or not when u touch it to a 12v power source. This seeing as how this guy that did it soldered the connection it seemed fine so I took a different wire and touch one side to my positive battery terminal and the other side to the solder, instead of clicking it started sparking don't know what that is but it was weird I thought I fried my ecu but apparently not. So what I thought it was the solenoid that went bad so my friend had and extra solenoid laying around and let me use it instead. I went to take the old one off and put the new one in resoldered the connection and went for a ride.... still no vtec so we went to the wiring in the ecu followed that wire back and apparently its hooked up to the right wire except there was also the power steering wire hooked up to it as well, so meaning one wire from vtec solenoid went to that birds nest soldered to the vtec wire and the power steering wire combined and had electrical tape around it, my question is, is that power steering wire supposed to be there? Can I just cut that power steering wire and just re solder the connection to the vtec wire? Maybe the power steering wire is interfering with the signal? My friend was about to do this yesterday with me and cut it but he's worried that might mess something up electrically so I decided to ask you guys, what do you think? Sorry for the long post and thanks ahead any questions on this just post it up this vtec crap is preventing me from making the power I want on the dyno
